Hi All; >From what I have seen & know of, the Astatic "G" push-to-talk stand was un-amplified. The T-UG8 PTT Stand was amplified but for hi-Z inputs. The T-UG9 PTT stand was amplified and universal, Hi-Z es Lo-Z. All stands could be mounted with a D-104 Xtal hi-z crystal mike head or a 10D dynamic or 10C Crystal or Ceramic, I forget which now. All good mikes, I used just a D-104 head on a Astatic stand(not PTT either) on my AM G-28 Gonset, works great! 73....... Rich WA2RQY
